Listings are grouped by category, with entries in alphabetical order. Each entry has the name of the group or resource; phone number(s); a contact name, if one is necessary; an address (all are in Waltham with an 02154 zip code unless noted); and a short description. Activities or services that are wheelchair-accessible have a wheelchair symbol. Other types of access- TTY machines for the deaf, ASL- or foreign language-interpretation- are also noted where applicable. If an organization has volunteer opportunities, those are outlined as well. An alphabetical index of all entries begins on page 51.
