All books may be borrowed by any member of the society. Loan period is two weeks, and fines may be imposed for overdue books. The books are brought to many of the showings, but if you'd like to request or reserve a particular book, email the librarian or ask the exec members at any of the showings.
The reviews are mostly written by the librarian (or a previous librarian), and express the reviewer's personal opinion of the books. Don't be put off if they didn't like a book; you might like it anyway. The rank insignias from Star Trek are used for ratings of the books (Captain as highest).
