As tdw has stated, if you need a field to hold more than 255 characters you need to use a Memo field, which can hold in excess of 64K. The problems with corruption that tdw cited were with earlier versions of Access (v97 and earlier, I believe) and have long since been resolved.
If a database is set up properly, text fields seldom need to be more than 255 characters long. One of the Cardinal rules to having a well designed, normalized database is that no single field will contain more than one individual piece of data. Data stored in Memo fields should be restricted to "notes" or narrative type information, such as a salesman's notes on a customer visit or a doctor's progress notes on a patient.
Working primarily in a Heath Care environment, I've used Memo fields extensively for a number of years, without ever having a problem. The secret is to follow one single rule:
Never, never, never place data in a Memo field if there any possibility that you will ever need to search, sort, parse or in any other way manipulate the data!
Because many queries perform some of these functions, you have to take care in using them in queries or they will be truncated to 255 characters. . Allen Browne has an excellent article explaining how to deal with Memo field and queries:
