For two decades, the PURDUE ONLINE WRITING LAB (OWL) has been providing hundreds of free resources for students.
Sponsored by the English Department at Purdue University, this online resource includes the areas of writing and teaching writing; research; grammar and mechanics; style guides; ESL; and job search and professional writing.
Tutorials of particular note include their APA and MLA style guides, ideas for avoiding plagiarism, business letter writing tool, and instructions for developing an effective resume.
The “Purdue OWL Vidcasts” connect to a YouTube channel providing dozens of short, instructional videos on topics such as writing, citation styles, rhetoric, and grammar.
Although some resources are designed specifically for Purdue students, the majority of materials are intended for all users.
A keyword search tool provides quick access to useful resources. The “Site Map” provides easy access to a master list of topics and links.
