pubfind.el is a PubMed/HubMed client in emacs.
这是我第一个elisp脚本。现在我可以不离开emacs而检索PubMed并通过HubMed的cgi程序获得文献的bibtex信息。文件源码如下:
This is my first elisp script. Now I can search pubmed then get bibtex entry from cgi of hubmed in emacs. I attached the source code below:

;;; Commentary:
;; This packages provides an Emacs Lisp interface to
;; searching/obtaining BibTeX entry from the online source.
;; Currently concerned source isv
;;
;; o NCBI entrez
;; o HubMed
;;
;; On invocation, the function pubfind-get-by-query queries the user
;; for a journal, volume and page, then return the corresponding
;; BibTeX entry. While pubfind-get-by-id fetches the BibteX entry
;; according to the given pubmed id. The result will be a bibtex-mode
;; buffer with the results parsed out.
;;; Usage:
;;
;; byte-compile-file and put it in your load-path. In your
;; initialization file:
;;
;; (require 'pubfind)
;;
;; M-x pubfind-get-by-id/pubfind-get-by-query invokes the interface.
;;; Acknowledge:
;; This work is inspired by Nevin Kapur's `bibfind.el'.
