Did you know? All library books have LC subject headings (permanent hashtags).
For example, the book record for "Concussion Inc" includes the following subject headings, which suggest other ways to find books about football injuries.
Articles in library search engines (databases) like Academic Search Complete have hashtags called thesaurus terms. They help narrow down results. Thesaurus terms are located to the left of result list.
