Rue, H., Martino, S., & Chopin, N. (2009). Approximate Bayesian inference for latent Gaussian models by using integrated nested Laplace approximations. JRSS-B, 71(2), 319–392.
The INLA paper. Defines latent Gaussian models, the Laplace approximation scheme, CCD for hyperparameter integration. Read §2–3 for the spine of the algorithm.
Lindgren, F., Rue, H., & Lindström, J. (2011). An explicit link between Gaussian fields and Gaussian Markov random fields: the stochastic partial differential equation approach. JRSS-B, 73(4), 423–498.
SPDE. The Matérn–GMRF link via Hilbert space projection. §2–4 are the theory; §5 gives the FEM matrices you need to reproduce (C, G₁, G₂).

The R-INLA SPDE interface paper. Reference for how the API was shaped.
Lindgren, F., Bolin, D., & Rue, H. (2022). The SPDE approach for Gaussian and non-Gaussian fields: 10 years and still running. Spatial Statistics, 50, 100599.
The review of the SPDE approach. §4 covers non-stationarity and non-Gaussian extensions we probably won't implement in v1 but must understand to avoid painting ourselves into a corner.
Simpson, D., Rue, H., Riebler, A., Martins, T., & Sørbye, S. (2017). Penalising model component complexity: A principled, practical approach to constructing priors. Statistical Science, 32(1), 1–28.
PC priors. This defines the prior parameterization used for precisions, ranges, and mixing parameters throughout R-INLA. Required reading.

PC priors specifically for SPDE–Matérn (range and σ). Phase 4 deliverable.
Sørbye, S. H., & Rue, H. (2014). Scaling intrinsic Gaussian Markov random field priors in spatial modelling. Spatial Statistics, 8, 39–51.
Why and how to scale intrinsic GMRFs.
scale.model = TRUEcomes from here. Hyperparameter interpretability across graphs depends on this.

The disconnected-components fix. Without this you silently compute wrong posteriors on graphs with islands/isolated nodes.
