This is the Styletips project, which provides useful advice to editors on writing style and formatting in bite-size chunks from the Manual of Style and related pages. For the complete schedule of Styletips, see below.
Please place suggestions on the Talk page. The objective is to keep the focus of each tip narrow and to express it simply and briefly.
The letters in acronyms and initialisms are generally not separated by points or spaces (GNP, NORAD, OBE, GmbH). Points and spaces that were traditionally required have now dropped out of usage (PhD is now preferred over Ph.D. and Ph. D.).
