Hang the presidential logo and use the unified logo. According to the "Administrative Measures for Staff Libraries of the All-China Federation of Trade Unions (Trial)", the construction of staff libraries named by the All-China Federation of Trade Unions requires hanging all-president signs, using unified signs, having special venues, supporting bookshelves, tables and chairs, and computers with Internet access: the number of books (including newspapers and periodicals) is not less than 3,000, which has the function of providing digital reading services for employees. There are no fewer than/kloc-0 kinds of digital reading platforms with formal copyright (such as electronic staff library), and the trade union deploys staff at the same level to engage in the daily management of the staff library, with standardized book borrowing and management systems and corresponding funding guarantee and operation mechanism.
