The Lanier collection is organized into eight series:

  1. Biographical Information
  2. Correspondence
  3. Photographs
  4. Publicity
  5. Preparatory School Material
  6. Programs
  7. Published Material
  8. Miscellaneous

The Biographical Information includes pieces written by others on Lanier as well as copies of her resumé, personal memories of the Preparatory School after 25 years, information regarding her 55th class reunion from NEC, annotated folders she used for organization, and other items regarding her legacy.

Correspondence includes letters to and from Lanier dating 1941–2001. Most
exchanges are between Lanier and colleagues; however, there are some items of correspondence between various members of Lanier’s family which are not directly to or from her.  A sizeable portion of the correspondence regards Lanier’s retirement and death.

The Photographs show Lanier over the course of her career as well as people
influential in her musical development

Publicity material covers Lanier’s performance career and includes sketches for her publicity picture.

Most of the collection consists of material regarding the Preparatory School.  This includes school catalogues, curriculum guides, information for involved parties, and planning material. Of special note is a group of writings by Louis Krasner done while he taught at NEC.  

The Programs cover concerts by Lanier and her students both at NEC and other locations. This series contains newspaper clippings regarding concerts in which Lanier performed.  There are also a few graduation programs from NEC and the Preparatory School.

The Published Material consists of not only clippings regarding Lanier’s
performance career but also NEC and the Preparatory School, along with other
music schools in the area.

Miscellaneous incorporates items that did not fit smoothly into other series.  Items here include information regarding the National Guild of Community Schools of the Arts and items of interest to Lanier.
