Islesboro (57B) has 1 runway. Runway 01/19 is 2,400 ft long and 50 ft wide. The surface is asphalt. The field elevation is 88.3 ft MSL. No control tower is published for the field.
No ILS runway ends are published. That means you should plan for non-precision or visual work only, using the current FAA Chart Supplement for the latest airport data. The only runway-specific operational note in the facts is noise abatement. Pilots are asked to maintain runway heading to 1,000 ft AGL. That matters on both departure and go-around.
Use the runway numbers as published. Runway 01 is the northbound end. Runway 19 is the southbound end. The listed magnetic headings are 347.882228289015° and 167.882228289015°.

Traffic pattern
Pattern altitude is not published. For light piston operations, use the standard 1,000 ft AGL unless local procedures say otherwise. At this field, that works out to about 1,088.3 ft MSL based on the published field elevation. No tower is published, so self-announce and sequence with other traffic as needed.
The key pattern note is the noise abatement procedure. Maintain runway heading to 1,000 ft AGL. Keep that in mind on departure and after a missed approach. No right-traffic exception is published in the facts. No special pattern altitude for a specific runway is published either.
Every end, one page
Each runway end has its own page with wind component, traffic pattern geometry and ILS for that specific direction.
