Started my personal modpack and it spawned several books from several mods, and I was able to put all of them on my Bibliocraft bookshelf except for the "Engineering Diary" set up by Eureka. I don't have any other Eureka books so I don't know if it's universal.

it's odd it is an itemBook so i don't know what the requirement is for an item to go intro the bookshelf

Maybe a comparison with Chromaticraft, Tinkers Construct, Withery, etcs
book codes would reveal the answer?

yeah i'll take a look at that later

imo, since they didn't prove any kind of api (that i could find) or state the requirement for the bookshelf to accept a book and that they got some asset for other mod, i think it's their side.

they did state in their about page about some config options though

Compatibility with mods is also a concern for all blocks involved in this mod. To ease that I added several config options to easily add compatibility to many items.

Confirmed. To fix, add diary to the list of acceptable books in the bibliocraft config.
example
These are the keywords that are compared against the item names to determine if the item can be placed on a Bookcase. Add more keywords if needed.
S:AllowedBooks=book, map, journal, plan, thaumonomicon, necronomicon, lexicon, print, notes, spell, library, tome, encyclopedia, diary

Proof

Maybe it should help if you just rename the item to Engineering Notes, since notes already in the list by default. But maybe - just maybe - it's a BiblioCraft enhancement issue, so I recommend you to ask @Nuchaz if there is a way to provide an API to ask bookshelves to accept your book. I definitely want to see this book on my bookshelf too :-)

Anyway, @Voxel-Friend 's workaround should be enough until this get fix from any side.
