A teaching case library of clinical pharmacy was constructed to improve case teaching for pharmacy residents. Through establishment of draft requirement and organizing a group of authors consti-tuted by preceptors of pharmacy residents

the teaching cases were written

the contents and forms of which were assessed by teaching demonstration

interactively examined and revised by fellow teachers

audited and screened by senior pharmacists

and thus a case library was collaborated

processed and established. Finally

a case library was formed

which included 11 systems

such as endocrine

cardiovascular and neu-rological systems

and 32 cases of drug treatment for common diseases in each system. The construction of case library has enhanced the teaching consciousness and skills of resident pharmacists' teaching team. This case library will become an important resource for teaching and scientific research in the future.
