Stuck on Book puzzles

[十字的蓝]

I finished almost every environmental puzzles except those books . I don't understand what that means. Who can help me .

[♥♥♥♥ Goblin]

I haven't solved them yet but here are my thoughts:

1. They each have a different number of lines on the side. Books have 3, 4, 5, 6, and 7 lines. Could this be the order of the code?
2. The version/edition/bottom code perhaps is the row/column combination? ie. vol 2, 1st edition = row 2, col 1? A,B = row 1, col 2?
3. Colours are different and seem to match the colours of the Filament game icon which has 6 colours. Could this indicate the order of the code? (Only 3 colours match, red, purple, yellow; no dark blue or brown in the game icon)

Plug: I have the books side by side in my guide (under other objects at the end): https://steamcommunity.com/sharedfiles/filedetails/?id=2077644045

Thanks for the images of the books! I figured there was a 5th one given the hint indicator, but had not taken a screen capture when I found it as my game crashed regularly on picking up some items (due to low vram) and I'd forgotten where it was. But I remember seeing the Apple one. Thanks to you I was able to acquire my Library card.

The notes by user "C. Goblin" below are very close to being correct. However, the color(3) should not be important, and (2) is not about 'row' 'column'. I've put some notes below, but I apologize if the hints in my comment below are hard to read or if the text is long. I've used a lot of lazy/unique grammar. Normally I try to simplify what I write if there could be any chance language barrier, but I started writing this before realizing. If it is a problem then just let me know and I can clarify later. Unfortunately I do not remember my 4 years of studying Chinese because I do not practice writing it often. Many years have passed. I am sure that your English writing is better than my Chinese writing. If language becomes a problem, then let me know and I can try to simplify what I've written. If language is not a problem, then sorry for mentioning it.

Quick response: Line count is indeed important :) the second point is dealing with the correct numbers, but the spatial aspect of row/column did not match the solution in this case, think more like the other puzzles involving hex to indicate a pillar. While the colors is an interesting theory, it's taking information from quite far away from the books themselves, and likely should be last resort (I can say it's not relevant to save you some hassle, but that is a nice observation. It's likely to just be a color theory aesthetic choice, maybe as a lazy way to say what color value should we pick, oh we already have a nice pallet for the logo :) Also, let me say I reeeally like the style choice/quality of old/reference design/textured books; a lot, it made me smile!

Note: If you looked at an old version of the above guide, the black book was cropped and missing some details; it has since been fixed. Thanks CockGoblin! (also for others, there are a lot of other spoilers beyond the book images in the guide, though as of now they are just the images and not the solutions (though for some, the hunt is half of the work), as might be expected of the makings of a comprehensive guide; but just noted here to make others aware)

EDIT: I appreciate that the guide is just the images and some categorization currently and not the locations or all the details about the solutions exposed at this time. Maybe that will change later. But this solved my one missing screenshot book issue; which is much appreciated. The spoiler tags for the images "todo" per room would a great addition later.

General thoughts

My initial thoughts to consider (before reviewing all books) were that either editions or author's last names could indicate order (with The Filament corporation Magazine being a potential outlier (maybe by T or F). And similar to what's noted above, the line count being of interest (noting that the years of the magazine match the line count for that book which may not be coincidence but a hint to consider them. (which we already have)

The "A B" is very much like our normal input method indicators, hint: so best to keep that (and anything similar in nature to it) as for that purpose as a priority unless it doesn't work out after looking for patterns/input etc.

I was going to ask(1) since I did not have all the screenshots, but I think an update removed some of them (but could not remember), they may just be more of a hint or just junk left from creation.
(1)"Was it that the books without tick markings on the top and bottom (page sides) cover were the ones without edition or AB indicators ?" They are not on all books and I figured I might include them in line counts if it did not work out. they are not needed in the final solution, do not worry about getting screenshots of them

Additional Hints:

1. As expected, we must find something to indicate an order.
   • There are a few different information bits which are not "A B" indicator like/related.
     
   • I can confirm elimination of: the titles, or at least I did not use them
     
   • Hint(tested-and-not-correct): The author names is less of interest given the TFC Magazine does not have an explicitly noted author. (could try it, though maybe not on priority).
2. As expected, we must find info matching usual password column(pillar) indicators (identifier or directional; no direct visual mapping in this case)
   • We have remaining some details such as mentioned in others comments above The number of lines/gaps on the spines; Edition numbers; The yellow tick marks on the page-side-top and page-side-bottom cover (not related it seemed); Number of words in titles, alphabetical index of author names, etc, etc (last ones would seem much less likely to be expected to be figured out before other more obvious things, ie. very unlikely and very low-priority, would likely be a bit too obscure compared to all the other much stronger/prominent numbers/indicators.
     
   • Not all items have an "A B" indicator, but do have other details, sometimes a "4" sometimes something else though, are the roman numeral/number enough pillar indicators to be a password.. could try it but the count seems low. Some don't have a number either (but blank one could be an outlier that will later make sense if the others all otherwise fall into place for a given approach.
     
   • Important hint but not solution: One book has nothing like the "A B" indicator whereas the others all have some extra info like it; this could be considered a way to eliminate that, but "A B" indicator is otherwise really really strongly suggesting in that case it's a pillar indicator. Maybe that book with nothing extra in that area is non important/needed (but I'll note that it is, and bigger spoileras you enter the password up to that point and then try to consider what pillar it indicates, it will make sense..
     
   • You may end up looking at candidate numbers and think "there's no way to touch this pillar and then the next one without touching another one, which is usually a good way to rule something out as being the next one in the list to touch (and thus ruling that out) except under scenarios where you have already split off groupings of pillars using your line, so you can get past/under something that has already been touched and split off by your filament-line. So while it can help when actually trying the combinations of pillars in order, it can't always be an indicator that some single pair lets say "9 B" can't be possible because you'd have to touch A in the process, except if you had already touched A prior. These numbers used in my example are not necessarily specific to this puzzle, but just chosen as an example.

I've compiled some potential data from the books into a table (unfortunately I only did it for my self to use linux tools to work with it instead of a spreadsheet, so it was only tab separated; which doesn't translate over to here so well in a copy paste but maybe someone will find it useful, there is no specific ordering to it as it is currently. Also it has major spoiler in that I've quantified some things as numbers which I did in advance and then sorted by various aspects in order of higher suspected chance to be the correct method.

I wanted to pay tribute for providing the image of the one book I'd lost which allowed me to complete this just now, so I'm making this a bit more obvious in the form of numbers; and since you're already working on a Walkthrough so probably trying to get it faster instead of take time to fully sort it out all without major hints. Though I've not stated specifics of where some came from, though they may be very obvious upon thought/inspection.

Supplements above: (I also happened to have written out some of the data on a per-book basis in the correct order initially, so that may help; I'm not specific here but I mean that the order of the books is NOT correct, but some other ordering that exists on per book basis -is- correct. My stating this is not too important to focus on, it's just to say this table may eliminate and spoil some of the work at the same time. Someone may wonder why I have two numbers in the "Bottom_Num" column in same cases, this is because one is the number indicated at bottom, the other is the other supplemental number I got from <somewhere> else on the book, which could vary per book (not implied by my original column name.

One more question : What means about spoiler?

[iceni2103]

Got the books puzzle:

Order them by the number of bands on the spine, then input the volume and edition numbers in sequence.
1 :: An apple in the face of Despair. by J.P.J Simmons (vol. 2, 1st ed.) - (3 bands) - 2 1
2 :: Introduction to space: it's mostly empty. by Thomas Olliver (A B) - (4 bands) - A B
3 :: An Olive on a Chair. by Lindsey Dixon (vol. 7, 5th ed.) - (5 bands) - 7 5
4 :: Harmony observation ports: How TFC gifted us our liberty. by Olivia Chernov - (6 bands) - 0 (since there is no volume or edition)
5 :: The Filament corporation magazine 1970 - 1979 (vol. 4) - (9 bands) - 4

full sequence : 2 - 1 - A - B - 7 - 5 - 0 - 4

Do not worry! Yes, tests should be a priority :)

One more question : What means about spoiler?

I have written some clarifications about my last comment.

When you asked: "What means about spoiler?". I was not sure which spoiler detail you ask about. Or if you are asking about all of it. So I decided it is good to summarize the confusing ones and the very last 'pastebin'. Sorry if some of my explanation is not needed. :)

User "iceni2103" wrote a short list of exactly which details from the books are needed, but also the exact solution at the bottom of the comment. If it is better to have the exact answer, then please feel free to read that. If you would like to try with only Hints first, then I have clarified some of my comments. Maybe it is also useful to practice reading. Though if it is too much time and text then I will not be bothered if you do not read it. I do not want to impact your studies or other time to play more of the game. :) I'm glad to continue, but another option is to check on the game developer's Discord. Maybe there are a few Chinese+English speakers there that could help faster during the same time of day. Otherwise, studying the exact answer in the comment by iceni2103 can be faster if a direct answer is desired. The very important parts of my comment are marked with a "*****".

Clarifications

**** A quick note: About the 'pastebin' table in my past comment. More details are at the bottom

"Bottom_Numbers" are like:
- 🅐 🅑 ("A B") 
-「VOL.2」第2巻。「VII」(7) ...
-「first edition」原书第1版。...
"Bottom Numbers" is not a special term. I just mean 底部的数字。/ 这本书的底部。Or any extra information on the spine of the book. I do NOT mean the small yellow line on the under-side/bottom.

I updated the table. I removed some unrelated details. They were just my extra notes when thinking about the puzzle. I left them because it could require some more challenge for the reader. https://pastebin.com/raw/CxVG77C1. More detail about the table are at the end of this comment. I tried to add some Chinese labels, but you probably already know what they mean. (Sorry if it looks strange. EDIT: Ah, I used「」out of habit from writing Japanese more often then Chinese in recent years.. I have been exposed. haha )

-----

I used the [spoiler] for different reasons.

• I hid some information from users that have never seen any books. Therefore in some places it is not an important hint for you. Only to stop new users from mistakenly reading if they have not discovered any books. (If they found the comment by Searching for something else.)
  
• I hid Library Card because it is part of the corrupted message. It is a small joke for people that have solved the puzzle. It is not needed to solve the puzzle.
  
• I hid important details so readers can think some and slowly read more detailed hints if needed. However, a lot of the remaining details in the [spoiler] text are useful. Reading only the text that is not hidden is probably not be enough detail.

-----

Below is a summary of some of my past comment details. You may already understand these parts. Details about the last spoiler in my past comment are further below.

***** Information that is needed for this puzzle:

• The number of lines on the book cover. (1)
  
• The 🅐 🅑 text ("A B") on the bottom look like hexadecimal. It is similar to other puzzles in the game that use hexadecimal. So we should use them the same way as the yellow paper note attached to one of the Terminals. However, that is only two numbers. We need to find many more.
  
• We need to decide what the order is.
  
• The only other information on the books:
  • Author name. The first letters of the names are not 0-1 or A-F. We can consider Alphabetical order, but I can confirm it is not important. (It is not needed.)
    
  • The Title of the books. Again, It is not needed.
    
  • The Book's Volume (vol.) number and Book's Edition number. Example: "first edition" -> "1st" -> 1
    
  • One that is not important: The years of 1970-1979 -> 9; It is not needed. It may be a hint because there are also 9 horizontal lines on the cover of that book.

While I tried to solve the puzzle I wrote "4 9" in my 'pastebin' data. IF the 9 was important/accurate, then I could remember it while solving it. (It is not important)

(1) I did not need these bottom markings[i.imgur.com] to solve it: I only needed the lines that are on the side with the text. My hand writing with a computer mouse is bad, so later added the digital text. haha

-----

Do you know what I mean here? :

This is about "hexadecimal" used in other puzzles. That part is important to understanding the "A B". I think you know that one, but I ask because if you do not know it, then it would not be a very helpful hint without more explanation.

Above is an unrelated joke about the Touhou "Double Spoiler" game name. :) I used two [spoiler], like [spoiler]"Do you want to read it?" [spoiler]Ok, you decided to read it![/spoiler][/spoiler].

This is a table of details from the books. The second URL is easier to read. It is the same information as the first URL. I used "?" in some places to mean I did not remember that detail for the book. I also used "?" if I could not easily read some of the text. That table shows many details that were not needed. But it does show some important details that are needed. The books in that list are not sorted in the correct order. The important part is to determine what order it should be in. Then to determine what details should be entered into the Terminal's password input. (Like "A B"). So I have converted details of "first edition" into "1". That may help shorten the time to translate or guess some details.
Actually, I have not tried viewing the books while in Chinese Language Setting mode.. Maybe I should verify it is still english on the book? I think it would still be english. The important part for you is to use information like that to determine the order and also to determine what part is used to enter into the password prompt.

Sorry. This is part of my past comment that will be confusing. It is confusing even in English. To be more clear: The "A B" and "7 5" are in correct order in my 'pastebin' table. It is "A" then "B". It is not "B" then "A". I said that because maybe someone will write "fifth edition" then "vol. 7". A user could think it is "5 7" but it is not. It should be "7 5" for this puzzle. I tried not to be clear because I did not want to draw too much attention to it. It is more critical for the Book with "1970-1979". If someone read it from the top to the bottom, it could be "1970-1979"-> 9. Then "4" from the bottom. It is not
"9 4". It should be "4 9". And truly, it should be just "4". This will be more clear as you try to input the password at the terminal. If you determine the correct order then when you get to that step it will be better understood.

-----

If you were only asking about the definition of the word "spoiler" - it is 劇透[zh.wikipedia.org]. I think you were asking about the meaning of what I wrote in the hidden text. I just realized it could be about the word, so I added this extra line of text.

I'm not sure if that helps clarify your recent question, but I hope it helps.

Regarding the small Lines/Ticks on the covers

To be more accurate regarding those bottom ticks/lines seen here[i.imgur.com]. We can say that they indicate the number of data points to take from each cover; however, I ended up finding it intuitive regarding the one "blank" cover with no similar data (based on an assumption which was reaffirmed during the act of entering them). This is similar for the 1970-1979 book. I just did not bother with them until a given consideration of an approach required some other detail to resolve a problem in the approach. I also had only taken screenshots of some of them; others had crashed my game before I could get the extra data, so I did not end up needing to return to gather that data point. For example, the 1970-1979 book's single 4; and the single tick on the otherwise 'blank' on the Harmony book It was just within reason for me to solve without it; if any of the books with two data points on them had indicated only one number should be used then it could be more of a concern. I still do not have all of the side screenshots so I can't ensure I don't have any thought about that incorrect at this time. They may also just be to further help draw attention to lines.[/u] I did not bother considering their positions across the edge or their width without all of them on hand.

I also had only taken screenshots of some of them; others had crashed my game before I could get the extra data, so I did not end up needing to return to gather that data point. For example, the 1970-1979 book's single 4; and the single tick on the otherwise 'blank' on the Harmony book It was just within reason for me to solve without it; if any of the books with two data points on them had indicated only one number should be used then it could be more of a concern. I still do not have all of the side screenshots so I can't ensure I don't have any thought about that incorrect at this time. They may also just be to further help draw attention to lines.[/u] I did not bother considering their positions across the edge or their width without all of them on hand. [/quote]

I finished it! (Please forgive some grammatical errors )
Luckily, I read your response first so that get away from the fate of being spoiled( I can retain the interest of solving puzzle or a part of it . After watching your hints , I observed this books about half an hour , written down some suspicious combination and had a try . One of them works .
I realize this environmental puzzle is no more complex than others like Periodic Table or Moss coad , instead , I fall into the misunderstanding . At first , I think each book represent for an independent puzzle or we need split joint all books in different colours . It's make me upset when I tried it over and over again but found nothing . So I asked for hints and focus on another hidden puzzles:)
In any case , thanks to your help I can figure out this puzzle ,now I only need finish the final hidden puzzle so that I can catch the Platinum (Though I haven't find where it is yet , hope I can finish it in two days :)
Digression :Unbelievable! I never spend 53 hours in a puzzle game before . This game seems like have special magic , even if there are a lot of puzzles make me mad , but some intentions of the game (I don't know what it is ) push me to overcome it , Amazing.

Nice! Yes, the book puzzle is the same as the other ones where the hint-symbol comes with a marking like ⚄. It can suggest that you need to have all 5 (or multiple) before it is possible to solve the puzzle. Indeed, it is no more complex than the others you mentioned. It just needs another perspective or guess on what the strategy is. The way the data is hidden on each book is a little different. In the beginning this makes it hard to decide if each piece is related. I'm glad you completed it! Only one more!

The game does a good job to pull you in. I think the variety of environment and main puzzles helps. If you do not immediately understand one puzzle then you can move on to other types, and the general strategy is the same. For one individual, some puzzles are very obvious, other puzzles may not be obvious, but often you can re-use your strategies. There can be a feeling of quick success sometimes. There can also be challenges to overcome. Most of the variations of the main puzzle types do not feel "cheap". It is not as if the variation is only added to slow you down or make more of the "same" content. It changes enough to still be interesting and allow for practicing the same type of path-finding strategies, but with new restrictions that still are unique. They did think well about which types to use in the end. As you said, there is probably a bit more magic to it as well. The plot mystery and environment aesthetic help too.
