Currently, when you go into the item record for a book there is so much useless information yet trying to simply see all the books in that series isn't listed. There is an option for related resources which is library jargon to patrons and isn't the same as simply having a display of other books in this series to make it easier for patrons.
Also, instead of just telling me (unreliably) if a book is part of a series, it should tell people what number a book is in the series. Doing detective work to figure out if a book is in a series, where it is in the series, then where a patron can get the books in the series they want is exhausting and difficult for staff who didn't get MLS training.
